Answer to: Four pieces came off the camera when it fell off the shelf...I just had the same thing happen, and I think I fixed it! The two little black pieces cover the lens when not in use. There are little holes at 12:00 and 6:00 (as if you are looking at a clock). The little black pieces have notches that fit in the holes, and the two pieces fit together like puzzle pieces (almost like a yin/yang symbol). The larger black piece that is more square sort of snaps in over top of those. There are guide holes. Then the lens part snaps back on. You might have to fiddle with it to get those two small pieces to fit, but it should work. Good luck!
